A common “exploit” I’ve found in both of the Democracy games I’ve played (3 and 4) is being able to bring a group like State Employees or Patriots to 100% membership without backlash, slowdown, or any hindrance to achieving it as far as I can tell. Once a single group makes up the entire population, the game becomes dead easy to accomplish almost anything and any nuance or complexity is lost since everyone is X group, and X group is happy. Now I’m not saying this should not be achievable, but the ease that it can be done is a bit annoying for me. A few separate solutions I’ve considered are counter-group(s) backlash, a maximum membership cap of 90% or 95% (or adding a hindering curve to membership effect as it nears 100%), or a stronger polarization effect before such an arguably unrealistic unified utopia can be made.
I do not think such things should not be achievable given enough commitment and singular purpose, but they definitely should not be easy either
